Begin by preparing the lemon vinaigrette. In a small bowl, whisk together the lemon juice, Dijon mustard, minced garlic, Worcestershire sauce, anchovy paste (if using), and egg yolk (if using) until well combined.
Slowly drizzle in the olive oil while continuously whisking to create an emulsion. Season the dressing with salt and pepper to taste. Set aside.
Combine the torn Romaine lettuce, croutons, and half of the grated Parmesan cheese in a large salad bowl.
Pour the lemon vinaigrette over the salad and toss until the lettuce is evenly coated.
Sprinkle the remaining Parmesan cheese over the top of the salad for garnish.
